Hargreaves Lansdown recorded a 21% increase in profits in the year ended 30 June, driven by revenues from its Vantage platform.
The company's profit before tax was £152.8m, up from £126m in the previous 12 months, from total revenues of £238.7m, up from £207.9m.
Revenues within the Vantage division were up 16% to £185.7m, while overall net business inflows were down 9% to £3.2bn.
Meanwhile, the company took a £4.8m hit through Financial Services Compensation Scheme levy costs, up from £3.7 in 2010/11.
The total dividend has been set at 22.59p per share, up 20% on last year.
Alongside the results, the company has announced that co-founder Stephen Lansdown will step down from the board at the November annual general meeting, having been a non-executive director for the last two years.
Lansdown and co-founder Peter Hargreaves are amongst the UK's wealthiest people, after the former accountants turned the firm they founded 30 years ago into a FTSE 100 company with a multi-billion pound market cap.
CEO Ian Gorham said: "As investor confidence is heavily influenced by stock market momentum, our continued strong growth is a testament to the diligence of our company in focusing on clients and investing in new and innovative services.
"The key contributors to these excellent results have been the success of new services, careful husbandry of existing resources and cost control."
The profits for the year beat forecasts, with analysts at Singer Capital Markets predicting a profit before tax of £147.9m ahead of the results.
